Scientists create optical lens that can make users seem to disappear. Cloaking ability similar to Harry Potter, but these innovations are developed utilizing an optical lens.
Reported Phys, Monday (09/29/2014), scientists from the University of Rochester is developing innovations with an inexpensive cost. They create or cloaking (cloaking) in a way that is simple and involves a claimed new technologies.
"There are a lot of high-tech approach to cloaking and the basic idea behind this is to take the light and let it pass around something as if it was not there," said John Howell, professor of physics at the University of Rochester.
Howell and graduate student Joseph Choi developed a combination of four standard lens that makes the hidden object. "This is the first device that we know that can perform three-dimension, multi directional cloaking ongoing basis," said Choi.
In a test, they put objects in front diselubungkan a striped background (grid). As they look through the lens and change the angle of view, the grid shifts.
In a paper to appear in the journal Optics Express, Howell and Choi unveil a mathematical calculation for this type of cloaking type that can work for angles up to 15 degrees or more. They used a technique called the ABCD matrix.
The matrix illustrates the bend, how the light as it passes through a lens, mirror, or other optical elements. This technology is expected to be applied to assist the surgeon, so that doctors could see what he was doing behind his work when dissecting the patient.
